It's only been a few days since Valve announced its revolutionary Steam Controller along with Steam OS and Steam Machines, but apparently the configuration file for the Steam Controller was present inside everyone's Steam accounts (those who keep Steam updated) for at least weeks. NeoGAF user "iosefe" found the configuration file on his computer inside the folder where Steam was installed. (\Steam\controller_config). The configuration file mentions the touchscreen buttons and the triggers along with the trackpads.
